Hair cosmetic composition

Abstract

The hair cosmetic composition of the present invention, which is a one-agent type or a multi-agent type hair cosmetic composition, contains, the following components (A) to (D), the component (C) content, relative to the total composition of the hair cosmetic composition, being 0.1 mass % or higher and lower than 20 mass %:

• • (A): a compound selected from the group consisting of glyoxylic acid, a glyoxylic acid hydrate, a glyoxylate salt, and a glyoxylamide;
  • (B): a phenolic compound having an electron-donating group on at least one m-position and having a hydrogen atom on at least one of the o-positions and the p-position, wherein the electron-donating group on the m-position may form, together with an adjacent carbon atom, a benzene ring optionally substituted with hydroxyl group(s);
  • (C): an organic solvent having a boiling point of 100° C. or higher; and
  • (D): water.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a hair cosmetic composition which can shape hair semi-permanently or permanently.BACKGROUND OF THE INVENTION[0002]Conventionally, semi-permanent or permanent deforming of hair is carried out through a technique such as using a reducing agent (e.g., permanent waving) or using a strong alkaline hair treatment agent (pH: 12 to 14), typically an alkaline relaxer. These techniques, however, are well known to considerably damage hair for a long period of time. In recent years, there has been developed a curly or frizzy hair straightening method employing a large amount of formaldehyde, as a method for semi-permanently or permanently deforming hair with less hair damage. However, the method, employing highly toxic formaldehyde, must be performed with care due to the high volatility of formaldehyde. Thus, the method is not a preferred hair treatment method.[0003]For overcoming these drawbacks, there have been investigated such tre...
